In my last post, there was a statement that "the denial of communion is intimidation".
The speakers were Catholic. When they say Communion, they meaning the ceremony involving "taking of the Eucharist" - the bread transmuted into the literal body of Christ.
As a Protestant, I would speak of "communion" - fellowship and meeting with other Christians.
The Catholic version is more serious. Denying the Eucharist is denying a means of grace, potentially damaging to one's eternal state. Total eviction from the Church could be interpreted as causing one to lose one's salvation (if you believe there is no salvation outside the Church).
But, there is agreement that some form of discipline is needed, as commanded by Matthew 18:15-19.
That gets back to the meaning of love. Is it loving to deny the truth? To carry on meeting and associating with someone who disagrees with fundamental teaching? Is not the most loving thing to be truthful? Even if it is hard.
Perhaps feeling the hard consequences will bring someone to right thinking.
